ELECTRICAL CURLING-IBON HEATER.

Application fled August 31, 1921. Serial No. 497,388.

To all whom it may concern:

Be it known that I, AUoUs'r Orrnn- MAN, a citizen of Germany, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Electrical Curling-Iron Heater, of which the following is a specification, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to an electrically heated hollow device in which curling irons or other articles may be moderately eated, the invention having reference more particularly to a curling iron heater that 1:; designed to be placed and used where most convenient in hair-dressers apartments or elsewhere.

An object of the invention is to provide a heater which shall be so constructed as to be convenient for use for various purposes when moderate heating is desired, and which shall be compact an adapted, to be conveniently repaired.

Another object is to provide an electrlcal heater which shall be so constructed as to be adapted for receiving and heating curling irons or other articles, and which shall be adapted also to radiate heat to articles on the exterior thereof.

A further object is to provide an electrical heater which shall be so constructed as to permit it to be used conveniently and safely by invalids or others to apply eat to portions of the body, and be suitable for drying small articles or pieces of fabric.

With the above-mentioned and other objects in view, the invention consists in a portable electrical oven adapted to apply heat both internally and externally, and having novel features of construction permitting ready renewal of the necessar heating element and connections thereo and, the invention consists also further in the novel parts and combinations and arrangements of parts as hereinafter particularly described and further defined in the accompanying claims.

Referring to the drawings,4Figure 1 is a perspective view of the improved heater as preferably constructed and sup lied with an electrical circuit connector; 1 2 is a horizontal central sectional and ragmentary plan of the heater structure; Fig. 3 is a fragmentary plan showing a portion of the heating element and its electrical connecthe casing are tions, and illustrating structural improvements permitting the electricalconnections to be easily made; Fig. 4 is an end view of the heater structure partially broken away; and, 'Fig. 5 is a fragmentar vertical central section, as on the line V in Fig. 4.

Similar reference characters in the different figures of the drawin indicate corresponding or like arts or eatures of construction herein re erred to in detail.

The improved heater comprises a substantial foundation slab 1 which preferably is oblong in plan and non-metallic or a poor conductor of heat to guard against injury to fine furniture upon which it may be placed, and preferably the slab is rovided with short legs 2 provided with ottom pads 3 permitting the legs to be placed upon furniture without scratching the surface thereof. Preferably the foundation slab has a top plate 4 thereon which may be metallic to impart mild heat to small articles which might be placed thereon. The oven portion of the heater comprises a head 5 having a leg 6 arranged upon the top plate 4 adjacent to one of the shorter ends thereof, and a head 7 having an aperture 8 thereon and having also a leg 9 arranged upon the plate 4 ad acent to the opposite shorter end thereof, the legs having screw threaded sockets 10 in their bottoms receiving bolts 11 inserted through the plate 4, the bolts having each a head .12 received into a recess 13 in the under side of the late. The top plate 4 is secured to the sl aib 1 preferably by means of screws 14. A casing 15 is rovided which conforms internally to t e contour of the heads 5 and 7, preferably being approximately oval and the end portions of the casing receives the heads respectively, the lower portions of the ends of the casing having notches 16 and 17 receiving the upper portions of the legs 6 and 9 respectivel The upper portions of etachably secured to the upper portions of the heads by means of screws 18 and 19 respectively, each head having a screw threaded socket 20 in its top receivmg the screw. The oven has a hollow core 21 therein that is shorter than the casing and correspondingly is approximately oval in cross-section, and one end of the core is removably inserted in the aperture 8 in the head 7. The casing 15 may be composed of aluminum when it is desired that it radiate heat, but it may in some cases be composed of other material which may not be a conductor of heat. The core 21 may be composed of brass tubing or other suitable material, and the opposite or inner end of the core has a head which preferably is composed of two plates 22 and 23 formed integrally with the wall of the core and bent inwards after slitting the wall so that the parts shall meet; and the end of the core has also two ivot cars 24 and 25 extending integrally rom the ends of the core wall. The head 5 has an arm 26 rigid on the central. portion of the inner side thereof that is received between the ears and connected thereto by means of a pivot 27 to permit relative movement of the head and the core when disconnected from the casing. The core 21 has a cover 28 thereon which is composed of suitable substance so as to be a non-conductor of electricity, and a heating coil 29 is arranged on the cover and insulated thereby from the core, the coil having terminal wires 30 and 31 having suitable insulating covers as may be required. The hea 5 is provided with two contact pins 32 and 33 w ich have threaded shanks 34 and 35 respectively that are suitably secured to the head and insulated therefrom, and the shanks are provided with binding nuts 36 and 37 respectively by which the terminals of the coil are secured to the inner portions of the shanks of the 1118. v p The conventional connector head 38 is connected with the contact pins and has a circuit wire cord 39 connected therewith, which is provided with a suitable plug 40 for having connection with an electrical socket for obtaining electrical current for the heater.

The heater is usually of small proportions, and when connecting the terminals of the heating coil to the contact pins the head 5 is turned pivotally as indicated in Figure 3 to afiord ample space between one of the shanks'and the head of the core in which to manipulate the binding nut and easily connect the terminal to the shank, after which the head 5 is swung over in the opposite direction to permit the remaining terminal to be likewise easily connected to the remaining contact in. This arrangement permits the user 0 the heater, who may not be an expert or may not be provided with special tools, to easily substitute a new heating element for one which may have been burned out, in man cases avoiding considerable expense inci ental to the employment of an electrician.

In ractical use the heater may be safely place upon polished furniture without resulting in damage thereto, atmospheric air being permitted to circulate under the foundation 1, and the foundation being of ample extent is not liable to he accidentally turned over when hastily removing articles from answers the heatin oven in which curling irons or other artic es may be properly heated conveniently. Various articles or substances may be placed upon the top of the casing to be slightly heated or warmed, and small articles may be slightly warmed upon the top plate 4:. The heater may be safely placed upon a bed and used as a foot warmer or may be so used when placed upon a floor. Also the casing of the oven may be placed in contact with portions of the bod to apply heat in case of illness or when or Various reasons a person ma desire it.
